That way we don't do the awful minimise on focus loss logic by default on XWayland where mode switching is emulated (like on the Wayland backend).
This fixes CS2, Dota 2 minimising on alt-tab when playing in fullscreen (which is really annoying when managing eg. Discord on another screen)
Some window managers can send garbage values during the initial mapping of a window, and need the position set again after mapping to ensure proper placement. Position requests sent before mapping can otherwise end up ignored. Ignore initial configure events when initially showing the window, and make sure that the position is set after the window is mapped, either when the window borders appear, or after the initial configure events in the case of borderless windows.
This also eliminates sending excessive/redundant move requests, which can cause strange behavior on some window managers, particularly if done before the window is actually mapped.
Fixes cases of incorrect initial window placement on GNOME + XWayland.
Fullscreen windows may be larger than the display if they were moved between differently sized displays and the new position was received before the new size or vice versa. Using the center of the window rect in this case can report the wrong display, so use the origin.
Fixes flickering and the window bouncing between different displays when moving fullscreen X11 and Wayland windows in certain multi-monitor layouts.
When moving a fullscreen window, the compositor movement animation can cause it to cross multiple displays, sending multiple display changed events, which can cause the window to jitter or be snapped to the wrong display in the case of exclusive fullscreen modes.
When moving fullscreen windows, only send the display changed event when the window isn't on multiple displays to avoid spurious display changed events.
The specific cases here were SDL_size_mul_overflow_builtin and
SDL_size_add_overflow_builtin, which are forced-inline symbols in
SDL_stdinc.h that have to exist, but aren't really part of the public API,
and thus shouldn't be exported as documentation.
If we need to extend this in the future, we'll make a second struct and
a second SDL_AttachVirtualJoystickEx-style function that uses it.
Just zero the struct and don't set a version.
Fixes#9489.
Connector names prior to v4 were sent via xdg-output, so use that if an older version of libwayland is present.
Additionally, ensure the output names are actually allocated before comparing the strings.
Use DBus to query Systemd to check if the pipewire-pulse service is in the "running" state. If it is, then it is certain that Pipewire is being used instead of Pulseaudio as the preferred system mixer.
If DBus support is not enabled or Systemd is not being used on the underlying system, this check will simply fail and the standard driver order will be tested.
